RO4003 PCBs are printed circuit boards (PCBs) made with Rogers' RO4003C material from the RO4000 series.RO4003C is a glass fiber reinforced, ceramic-filled material in a hydrocarbon resin system with the following properties:

Dielectric Constant (Dk): 

RO4003C has a dielectric constant of 4, which makes it useful in applications where impedance and signal transmission delay need to be controlled.

High Glass Transition Temperature (Tg): 

RO4003C has a glass transition temperature higher than 280°C, which indicates good thermal stability.

Multiple Thickness Options: 

A variety of thickness options are available, such as 0.008 inches (0.203mm), 0.012 inches (0.305mm), 0.016 inches (0.406mm), 0.020 inches (0.508mm), 0.032 inches (0.813mm), and 0.060 inches (1.524mm), to accommodate different design needs.

Low Coefficient of Thermal Expansion: 

Featuring a low coefficient of thermal expansion of 14 ppm/°C, it helps maintain the PCB's dimensional stability during temperature changes.

Good Thermal Conductivity: 

RO4003C has a thermal conductivity of 0.95 W/m/K, which helps dissipate heat.

High Electrical Strength: 

It has high electrical strength of 31.2 KV/mm and 780 V/mm respectively.

Processing Performance: 

RO4003C is easy to fabricate as its processing performance is similar to that of epoxy resin/glass cloth materials.
